Tobram-F is a combination drug (Tobramycin Sulphate and Fluorometholone) that has both anti-inflammatory and anti-bacterial effect. It enables the irradiation of bacteria along with response generated against it (inflammation).
MODE OF ACTION- Both the drugs have separate mechanism of action, and are independent of each other. Tobramycin irradiates the bacteria causing infection whereas Fluorometholone reduces the inflammatory reactions, which are in response to the foreign entrants (bacteria). Functions of both the drugs are discussed separately below-:
- TOBRAMYCIN SULPHATE- Tobramycin readily binds with the ribosomal pair, disabling it to produce m-Rna responsible for the protein formation in bacteria thus ensuring cell death. It also destabilizes the bacterial membrane by binding the 16s r-Rna thus the functional integrity of the bacterial cell membrane appears to be disrupted.
- FLUOROMETHOLONE- It controls the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of their common precursor, arachidonic acid. Arachidonic acid is released from membrane phospholipids by phospholipase A2. They inhibit edema, fibrin deposition, capillary dilation, leukocyte migration, capillary proliferation, fibroblast proliferation; deposition of collagen, scar formation associated with inflammation and delays the healing process.
